After the cuckoo chick pushed out the two natural hatchling, the man saved them and placed them into a surrogate nest. The problem was the foster parents ignored them, and the hatchling were either injured or didn't respond to the feeding call because they are too different of species. It is odd the cuckoo tracked them down and killed them specifically.

Does this mean Cuckoo mother does not abandon the baby until it knows the competition is eliminated. Often in these recording you hear the cuckoo in the background and that’s when you notice eggs or chicks are being evicted by the intruder?

[@user-cw9hb3ck4u]

Yes - they’re the laziest kind of parent. Lay the egg then have someone else bring it up - but still making sure you can jump in at any moment and be ‘mother of the year’ just because it benefits you some way…. They stay to see that their egg is looked after and fed until they’re of fledgling size. Usually if anything happens before then, the cuckoo will kill the entire nest and sometimes the parent birds too. I actually wondered if the male bird got harmed as there was all that screeching and squawking and then the black and white tail sticking up in the bottom corner of the nest - right as the cuckoo had first heavily landed on the nest and before we saw the cuckoo.

I can't even feel bad for some species that the Cuckoo targets because some mother birds are so dumb that they'll straight up watch their eggs get ejected from the nest and do nothing about it. It's literally survival of the fittest. Other birds like the Robin have evolved to fight off these invaders, but as long as birds like the Tit are dumb enough to keep letting it happen, it will be a successful method.
